How would one get a --nogpgcheck option to yum via puppet? I've tried

package { 'unsigned-package':
  ensure          => latest,
  install_options => ['--nogpgcheck'],
}

and

package { 'unsigned-package':
  ensure          => latest,
  install_options => ['nogpgcheck'],
}

but looking at the output from an agent run, yum isn't getting that option.

As an aside (and maybe the reason it's not working for me), how do I verify my puppet has the install_options feature?

I'm running puppet 3.3.0-rc2.
